This dialogue introduces type nihilism and token realism about the meaning of life.

In modern hospitals in developed countries, deaths are determined usually after a prearranged schedule of resuscitative efforts. By default, death is diagnosed and determined after “full code” or after the failure of intensive resuscitation. In end-of-life contexts, however, various degrees of less-than-full resuscitation and sometimes no resuscitation are allowed after the consent and shared decision-making of the patient and/or surrogates. The determination of brain death is a unique exception in these contexts because such an end-of-life care plan is usually not (...) offered until after brain death is declared. This essay analyzes and critiques three arguments for denying the family and/or surrogate a chance to consent to or forego the diagnostic protocol of brain death and choose an alternative end-of-life plan. First, opponents of consent for the determination of brain death argue that presenting it as a selectable end-of-life plan undermines the integrity of death determination. The second argument is that it is inconsistent to allow foregoing the determination of brain death when the determination of circulatory death is non-negotiable. The third argument is that allowing the patient/surrogate to forego the determination of brain death would jeopardize the fair and appropriate utilization of intensive care resources and potentially reduce organ donor pools. After closer conceptual examinations of these three arguments, this essay concludes that these arguments are conceptually and morally problematic. It defends an alternative patient-centered end-of-life care plan based on consent and shared decision-making. (shrink)

This chapter reviews fundamental ethical controversy surrounding the ongoing effort to revise the Uniform Determination of Death Act in the United States. Instead of focusing on the process of the revision itself, the chapter explores the underlying ethical debate over brain death that has been ongoing for many decades and finally culminated in this revision. Three issues are focused: the requirement for consent and personal exemptions before applying brain death for the diagnosis of death; redefining the areas of the brain (...) that have ceased to function in the definition of brain death; and codifying the American Academy of Neurology as the authority to issue the standards of the diagnosis of brain death. The chapter concludes that allowing the personal choice of death determination gives a pragmatic compromise to the disputed definition and practice of diagnosing brain death. So long as all risks and imperfections of the diagnosis are accepted through the consenting process, there is nothing ethically objectionable to continuing the current practice of diagnosing brain death as a successful tool to facilitate heart-beating organ donation without violating the dead-donor rule. By contrast, precluding personal choice and imposing legal restrictions to consent and exemptions would further erode public trust. (shrink)

This paper replies to Nanay’s response to my recent paper. My suggestions are the following. First, “should” or “ought” does not need to be deontic. Second, etiological theories of function, like provability logic, do not need to attribute modal force to their explanans. Third, the explanans of the homological account of trait type individuation does not appeal to a trait’s etiological function, that is, what a trait should or ought to do. Finally, my reference to Cummins’s notion of function was (...) intended to note that the homological account is permitted to use this non-etiological notion of function. (shrink)

This book, written by one of the leading Japanese scholars in the philosophy of agricultural science, examines the relationship between human life, the natural environment, and agriculture.

Rauszer and Sabalski proved in [2] that distributivity with respect to infi- nite joins and meets is a sucient and necessary condition making the RasiowaSikorski Lemma valid in distributive lattices. The main part of their proof is a direct construction of a required filter under distributivity. In this note we show that a generalization of the result can be obtained from the Rasiowa-Sikorski Lemma for Boolean algebras by using Gornemann’s result in [1] instead of a direct con- ¨ struction. Suppose (...) A is a distributive lattice and Q; R 2 A f;g. We call A complete if 8M 2 Q9 M 2 A and 8N 2 R9 F N 2 A. M 2 Q is -dis if 9 M 2 A and 8a 2 A a t M = m2M. N 2 R is F -dis if 9 F N 2 A and 8a 2 A a u F N = F n2N. is called distributive if every M 2 Q is -dis and every N 2 R is F -dis. Suppose A is complete and C; D A. By rC we mean the filter in A generated by C, in particular, let r; = ; = ;. is called complete if and , where 8M 2 Q 9m 2 MrC \ D[fmg = ;) 8N 2 R 9n 2 NrC[fng \ D = ;). (shrink)

The aim of this paper is to develop a new connection between naming and necessity. I argue that Kripke’s historical account of naming presupposes the functional necessity of naming. My argument appeals to the etiological notion of function, which can be thought to capture the necessity of functionality in historical terms. It is shown that the historical account of naming entails all conditions in an etiological definition of function.

Evolutionary theory has recently been applied to language. The aim of this paper is to contribute to such an evolutionary approach to language. I argue that Kripke’s causal account of proper names, from an ecological point of view, captures the information carried by uses of a proper name, which is that a certain object is referred to. My argument appeals to Millikan’s concept of local information, which captures information about the environment useful for an organism.

The social and cultural causes behind the widespread use and acceptance of robots in Japan are not yet completely understood. This study compares humans and robots in images gathered through Google searches in Japanese and in English. Numerous pictures obtained by the search in Japanese were found to have a human and a robot looking together at something else (“third item”), whereas many of the images acquired by search in English show a human and a robot facing each other. This (...) is similar to the composition of mother and child in paintings: in _ukiyo-e_ that was painted mainly in the Edo period of Japan, the mother and child are often depicted together viewing something other than themselves, whereas this is not the case in Western paintings of mother and child. It has also been pointed out that, in modern Western paintings, the world inside the picture is separated from the outside world, forming an independent microcosmos, whereas the inside and outside are continuous in Japanese paintings. These may indicate that, in Japanese society, robots are to a certain extent regarded as fellow human beings who can share the third item. In Western society, on the other hand, no code is embedded that can fix robots’ superiority or inferiority to humans, which would easily trigger an antagonistic view toward artificial intelligence (AI)/robots as threatening entities, as shown in most of Western literature and movies. We suggest that such cultural characteristics of Japanese society can contribute to enhance coexistence with AI/robots. (shrink)

This paper investigates the semantics of measure phrases in Japanese. Based on new data, we argue that the interpretation of measure phrases in Japanese is sensitive to scale structure such that (i) measure phrases are introduced by a degree morpheme that selects only for gradable predicates whose scale contains a minimal element (i.e., a lower closed scale) and (ii) violations to this restriction are repaired via coercion, which forces a comparative interpretation with a contextually determined standard and hence a minimal (...) element. We compare the Japanese facts to data in other languages and argue that the requirement of having a minimal element is not specific to Japanese, but universal. We show that languages may vary in how they deal with potential violations of this universal constraint, including coercion of a contextually recoverable derived minimal element (Japanese), ungrammaticality (e.g., Spanish, Korean, Russian), and a hybrid system of ungrammaticality for some adjectives and allowed constraint violation for others (e.g., English, German, Italian).

BackgroundThis essay provides an ethical and conceptual argument for the use of informed consent prior to the diagnosis of brain death. It is meant to enable the family to make critical end-of-life decisions, particularly withdrawal of life support system and organ donation, before brain death is diagnosed, as opposed to the current practice of making such decisions after the diagnosis of death. The recent tragic case of a 13-year-old brain-dead patient in California who was maintained on a ventilator for over (...) 2 years illustrates how such a consent would have made a crucial difference.MethodsConceptual, philosophical, and ethical analysis.ResultsI first consider a conceptual justification for the use of consent for certain non-beneficial and unwanted medical diagnoses. I suggest that the diagnosis of brain death falls into this category for some patients. Because the diagnostic process of brain death lacks the transparency of traditional death determination, has a unique epistemic structure and a complex risk-benefit profile which differs markedly from case to case, and presents conflicts of interest for physicians and society, I argue that pre-diagnostic counseling and informed consent should be part of the diagnostic process. This approach can be termed as “allow cardiac death”, whose parallel logic with “allow natural death” is discussed. I also discuss potential negative impacts on organ donation and health care cost from this proposal and offer possible mitigation. I show that the pre-diagnostic counseling can improve the possibility for well-thought-out decisions regarding organ donation and terminating life-support system in cases of hopeless prognosis. This approach differs conceptually from the pluralism of the definition of death, such as those in New Jersey and Japan, and it upholds the Uniform Determination of Death Act.ConclusionsMy intention is not to provide an instant panacea for the ongoing impasse of the brain death debate, but to point to a novel conceptual ground for a more pragmatic, and more patient- and family-centered approach. By enabling the family to consent to or decline the diagnostic process of brain death, but not to choose the definition of death, it upholds the current legal definition of death. (shrink)

Naturalistic teleological accounts of mental content rely on an etiological theory of function. Nanay has raised a new objection to an etiological theory, and proposed an alternative theory of function that attributes modal force to claims about function. The aim of this paper is both to defend and to cast a new light on an etiological theory of function. I argue against Nanay’s “trait type individuation objection,” suggesting that an etiological theory also attributes modal force to claims about function. An (...) etiological theory of function can be thought to analyze claims about function with modal force, not relying on any theory of counterfactuals. (shrink)

The aim of this essay is to elaborate philosophical and ethical underpinnings of posthumous diagnosis of famous historical figures based on literary and artistic products, or commonly called retrospective diagnosis. It discusses ontological and epistemic challenges raised in the humanities and social sciences, and attempts to systematically reply to their criticisms from the viewpoint of clinical medicine, philosophy of medicine, particularly the ontology of disease and the epistemology of diagnosis, and medical ethics. The ontological challenge focuses on the doubt about (...) the persistence of a disease over historical time, whereas the epistemic challenge disputes the inaccessibility of scientific verification of a diagnosis in the past. I argue that the critics are in error in conflating the taxonomy of disease and the act of diagnosing a patient. Medical diagnosis is fundamentally a hypothesis-construction and an explanatory device that can be generated under various degrees of uncertainty and limited amount of information. It is not an apodictic judgment as the critics presuppose, but a probabilistic judgment with varying degrees of plausibility under uncertainty. In order to avoid this confusion, I propose that retrospective diagnosis of a historical figure be syndromic without identifying underlying disease, unless there is justifiable reason for such specification. Moreover it should be evaluated not only from the viewpoint of medical science but also in a larger context of the scholarship of the humanities and social sciences by its overall plausibility and consistency. On the other hand, I will endorse their concerns regarding the ethics and professionalism of retrospective diagnosis, and call for the need for situating such a diagnosis in an interdisciplinary scope and the context of the scholarship of the historical figure. I will then enumerate several important caveats for interdisciplinary retrospective diagnosis using an example of the retrospective diagnosis of Socrates for his life-long intermittent neurologic symptoms. Finally, I will situate the present argument in a larger context of the major debate among the historians of medicine and paleopathologists, and discuss the similarities and differences. (shrink)
